Based on Mr. Dunn's suggestion, I've also bought and used potassium nitrate.
It cost next to nothing.
Not for retail - I wish. For myself.

If someone doesn't want caffeine with the Nitratene then we offer D-Pol. A Nitratene only product would be a tough sell on the market solo. I doubt the amount of people turned off by condense with the caffeine product is minimal sense it is a pre-workout. Actually makes it one of the lower stimulants on the market haha
I'd say the majority of people take 1.5-2 servings of condense daily though so the BA gets to the level needed as seen in studies, though I believe it was shown best spread out in the day in some of them. Something over looked in Condense is the Betaine which isn't super sexy but does have some solid science behind it.
Id say it's one of my favorite products I used and would be regardless of affiliation. I have a lot of people around me that use it religiously as well.
